Abstract

In this research, The effect of  superthermal of ions was studied on in polarization force Attributable  of deformation of the Debye sheath around the dust grains in dusty plasma with Boltzmann distributed electrons and kappa distributed superthermal ions, and negatively charged dust grains.

Two opposite directional Kortewg-de-vries (KdV) equations  are derived and the phase shift due to collision is obtained using the extended version of Poincare´-Lighthill-Kuo method.          It is found that superthermal  parameter have been shown to be play a significant role on polarization of dust grain that the ions are the constituent of the sheath formed around the grain. These changes in polarization force effect on amplitude, width of colliding solitary waves, In addition to the phase shifts resulting from the collision.
